Scottish star Burns defends his WBO world lightweight title against Londoner Mitchell, at Glasgow’s SECC, on September 22.

And he’s been drawing inspiration from Scotland’s sensational 1990 Five Nations victory over England at Murrayfield.

The shock 13-7 win earned Scotland the Grand Slam and the video of the ‘Rocky’-style upset by David Sole’s team is now being viewed regularly by Burns.

He said: “Like any Scottish sports fan knows, that win by the national team is probably one of our most famous wins to date in sport against the English.

“Although I was only seven at the time, I remember the passion of the Scottish players and what it meant to win a match where they were the clear underdogs.

“They showed real fighting spirit and everyone still remembers and talks about the win today – and the game was more than 20 years ago!

“My dad still has a video of the match and I have been watching it.

“Just seeing it stirs up the passion in me to beat Mitchell.

“Seeing the iconic images of David Sole leading the team into battle and singing ‘Flower of Scotland’ really got me choked up.

“It’s been great to watch it over again. It is a real morale-booster.

“The only other time I feel like this is when I watch Rocky IV!”

Mitchell, meanwhile, will be hoping for inspiration from the round ball game today, when he makes a guest appearance at his beloved West Ham’s lunchtime Premier League game against Fulham at Upton Park.

The ‘Dagenham Destroyer’, who fought Michael Katsidis for the world title at the Boleyn Ground two years ago, can’t wait for kick-off.

He said: “It’s fantastic West Ham are back in the Premier League. They’ve fought hard to get there.

“I have had to do the same to get back and challenge for a world title again and seeing the Hammers back in the top flight has given me a boost.

“I couldn’t achieve my dream of winning the world title against Katsidis, but I would love to return to hold the belt up in front of the West Ham crowd after I beat Burns.”
